DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any way.

[0028] The water tank provided by the embodiment of the present utility model is as follows Figures 1 to 6As shown, the water tank comprises a shell 100 provided with a through hole 110 and a matching part, the matching part is arranged radially apart from the through hole 110; and a supporting leg 200, the supporting leg 200 comprises a body part 240, a connecting part and a supporting part 250, the supporting part 250 is arranged at one end of the body part 240, the connecting part is arranged between two ends of the body part 240, the body part 240 is arranged through the through hole 110, the connecting part is connected with the matching part, the supporting part 250 is arranged outside the shell and supports the supporting surface.

[0029] The water tank, the shell 100 is provided with a through hole 110 and a matching part, the matching part is arranged radially apart from the through hole 110, the body part 240 is arranged through the through hole 110 and is provided with a connecting part, the connecting part is connected with the matching part, the supporting part 250 is arranged outside the shell 100 and supports the supporting surface, so that the supporting leg 200 supports and fixes the shell 100, the connecting part and the matching part are connected outside the shell 100, which is convenient to operate and has low difficulty, so that the assembly efficiency of the water tank is improved.

[0030] In some examples, as shown in Figures 2 to 6 The matching part comprises a matching hole 120, the connecting part is formed by extending outward from the side wall of the body part 240, and the connecting part is connected with the matching hole 120 by plug-in connection, clamping connection or fastener (such as screw, etc.) connection outside the shell 100, which has simple structure and is easy to manufacture.

[0031] In some embodiments, as shown in Figures 4 to 6 The side wall of the body part 240 is formed with an opening 241, and the connecting part is formed by extending outward from the edge of the opening 241, which has simple manufacturing process.

[0032] In some embodiments, as shown in Figures 2 to 6As shown, the fitting part includes the fitting hole 120, the connecting part includes the plug 210 and the stopper arranged on the plug 210, and the plug 210 is inserted into the fitting hole 120. During the process of inserting the plug 210 into the fitting hole 120, the stopper is extruded from one side of the fitting hole 120 to be clamped on the outer end face of the other side of the fitting hole 120 through the fitting hole 120, so as to prevent the plug 210 from being pulled out of the fitting hole 120 (i.e., when the water tank is poured, the plug 210 is easy to be pulled out of the fitting hole 120, and the stopper is used to prevent the plug 210 from being pulled out of the fitting hole 120), so as to realize the clamping and fixing of the supporting leg 200 to the shell 100. During the process of inserting the plug 210 into the fitting hole 120, the hole wall of the fitting hole 120 extrudes the stopper, so that the plug 210 is elastically deformed, thereby realizing the movement of the stopper from one side of the fitting hole 120 to the other side of the fitting hole 120 through the fitting hole 120; after the stopper moves to the other side of the fitting hole 120, the plug 210 is reset under the action of the elastic restoring force of itself, so that the stopper is clamped on the outer end face of the other side of the fitting hole 120, thereby realizing the clamping and fixing of the supporting leg 200 to the shell 100.

[0033] In some examples, as shown in Figures 2 to 4 As shown, the penetrating hole 110 and the fitting hole 120 are located on the bottom wall of the shell 100, the body part 240 is arranged vertically, the lower end of the plug 210 is located below the fitting hole 120 and connected with the side face of the body part 240, the upper end of the plug 210 is located above the fitting hole 120 and spaced from the side face of the body part 240, and the common hole wall between the fitting hole 120 and the penetrating hole 110 is abutted downward on the plug 210, so as to realize the stable upward support of the plug 210 to the hole wall of the fitting hole 120 (i.e., realize the stable upward support of the plug 210 to the shell 100), and the stopper is abutted downward on the outer end face of the fitting hole 120 facing upward, so as to prevent the plug 210 from being pulled out of the fitting hole 120, thereby realizing the clamping and fixing of the supporting leg 200 to the shell 100. This scheme is simple in process and convenient to operate. As shown in Figure 5 and Figure 6 As shown, the plug 210 is a folded rib plate including a horizontal section and a vertical section, the vertical section is located above the horizontal section, the horizontal section connects the lower end of the vertical section and the side face of the body part 240, and the stopper is arranged on the vertical section, and the common hole wall between the fitting hole 120 and the penetrating hole 110 is abutted downward on the horizontal section.

[0034] In some embodiments, as shown in Figure 4As shown, the stopper is a convex hump 220. The lower end surface of the convex hump 220 is flat and abuts the upward-facing outer end surface of the mating hole 120. This prevents the insert 210 from slipping out of the mating hole 120. Alternatively, the convex hump 220 can be formed by stamping, which is a relatively simple process. Alternatively, the convex hump 220 can be located on the side of the vertical section of the insert 210 facing the main body 240; or alternatively, the convex hump 220 can be located on the side of the vertical section of the insert 210 facing away from the main body 240. All of these configurations achieve the objectives of this application and do not depart from the design principles of this utility model. These descriptions will not be repeated here and should fall within the scope of protection of this application.

[0035] Among them, such as Figures 4 to 6 As shown, the insert 210 is provided with a first guide structure 211, which is configured to guide the insert 210 into the mating hole 120, thereby effectively speeding up the assembly of the support leg 200 and the housing 100. Alternatively, the first guide structure 211 may be a guide slope provided at the upper end of the vertical section of the insert 210; alternatively, the first guide structure 211 may be a guide curved surface provided at the upper end of the vertical section of the insert 210; all of the above configurations can achieve the objectives of this application, and their purpose does not deviate from the design concept of this utility model. These descriptions will not be repeated here, and all of them should fall within the scope of protection of this application.

[0036] Furthermore, if Figure 4 and Figure 5 As shown, the bump 220 is provided with a second guide structure 221. The second guide structure 221 is configured to guide the bump 220 from the lower side of the mating hole 120, through the mating hole 120, and to the upper side of the mating hole 120. This can also effectively speed up the assembly of the support leg 200 and the housing 100. The second guide structure 221 can be a guide slope provided on the upper end of the bump 220; or the second guide structure 221 can be a guide curved surface provided on the upper end of the bump 220, etc. All of the above can achieve the purpose of this application, and their purpose does not deviate from the design concept of the present utility model.
